Abstract

Longitudinal wire guide (4) for feeding a group of parallel steel wires in a specified X-direction, with a large number of sets, consisting of a lower LD guide lever (7), an upper LD guide lever (8), a compression spring (5) acting between the two, and with a lateral LD guide (10), wherein the sets are arranged to be steplessly displaceable relative to one another in a Y-direction perpendicular to the X-direction, and the plurality of sets are arranged on a carriage which can be driven in the X-direction.

Line wire guide for feeding a

Set of parallel steel wires

The invention relates to a longitudinal wire guide for feeding a group of parallel steel wires in a predetermined X direction

tion.

The state of the art in the production of industrial mesh and reinforcement mats (e.g. fence mesh, screed mesh) in automated welding machines with wires cut to length is an entry-side feed system, an entry-side wire guide and an exit-side advance system. Until now, longitudinal wires have been fed to a machine on the inlet side, with fixed guide elements defining the distance between the longitudinal wires of a mat plane. Solutions of this type are disadvantageous because they are difficult or impossible to adjust

or are customizable.

The object of the invention is to transport a group of line wires quickly and precisely in cycles in the direction of a welding machine, while at the same time ensuring that the distance between the line wires can be adjusted sufficiently precisely and quickly.

The longitudinal wire guide according to the invention achieves this by

that it has a variety of sets consisting of

Carriages are arranged, which can be driven in the X-direction.

In one embodiment, the plurality of clothings are arranged together on a frame, on which they can be moved together in a Z-direction, which is essentially perpendicular to the Y-direction and to the X-direction, by means of a height adjustment

In addition, the drive of the carriage and a closing of the lower LD guide levers and the upper LD guide levers can be cycled by a controller in order to transport a group of parallel steel wires in repeated steps in the X direction.

The invention is explained in more detail below with reference to an embodiment shown in the drawings. 1 shows a side view of a set for the line wire feed, FIG. 2 shows a schematic side view of a line wire feed, and FIG. 3 shows a front view of a series of

Line wire feeder sets.

As shown in Figures 1 and 2, there is a line wire feed

from a fixed base frame 1 with a height

(Z-direction) adjustable frame 2, in which a in the X-direction

often produces variable transverse wire spacing.

A set of a longitudinal wire guide 4 is formed from a lateral longitudinal wire guide 10 and at least one lower LD guide lever 7 and an upper LD guide lever 8 . The levers form intermittently closing tongs that push the LD in the X-direction. The LD lower guide lever 7 may be integrally formed with the LD side guide 10 . The lateral LD guide 10 is at least an opening, a slot or the like for an LD that guides its deflection in the Y direction

prevented.

The longitudinal wire panel is pressed into the individual lower and upper LD guide levers 7, 8 by means of one (or more) compression springs 5 (optionally also hydraulic, pneumatic, electric cylinders), whose spring force acts in the direction of arrow F and closes the lever and held. All longitudinal wire guides 4 are opened, i.e. the clamping force is deactivated together via two pressure strips 11, which extend in the Y direction and all lower and upper LD guide

A height adjustment 12, preferably electrically, is provided for the exact longitudinal wire height in the Z direction and additional functions. The longitudinal wire height is determined by the support point of a longitudinal wire 6 on the respective lower LD guide lever 7, which is connected via an LD guide holder 9 with the height

The sets of longitudinal wire guides 4 can be moved along a common shaft 13 in the Y direction in order to change the distances between the LD 6 and feed them to the welding machine. Alternatively, instead of a shaft 13, dovetail guides, T-slots or equivalent can be used. This can be done for all or only individual LD 6, specifically in periods of standstill that occur during continuous production and while the family of LD 6 is advanced in the X-direction at regular intervals.

If the diameter of the LD 6 used and/or the transverse wires changes (typical diameters are between 2 and 8 mm), all of the longitudinal wire guides 4 are raised or lowered by the required difference in the Z direction. According to the invention, this can also be done during ongoing production, e.g. if the LD diameter of two directly consecutive

of the wire mesh mats to be produced changes. The tactable longitudinal wire guide 4 therefore advantageously combines

The line wire diameters are variable, since a welding machine with a line wire guide 4 according to the invention can change over automatically due to the design. A changeover of the longitudinal wire division is not automated, but it is also extremely simple in accordance with the one presented here

Shape.

The longitudinal bar panel can be picked up steplessly in the Y-direction. After it has been picked up, the group of longitudinal bars can be guided with variable distances in the Y direction, since the longitudinal wire guide 4 is equipped with separately acting clamping force application and with stepless clamping force deactivation acting over the entire width of the mat. The application of the clamping force by means of the upper and lower LD guide levers 7, 8

is gentle on materials and surfaces.

If necessary, the longitudinal bar panel can also be transported back in the X direction. This is programmed in the controller, but does not require any modifications to the device. The group of longitudinal bars can also be aligned in the X-direction on the welding electrodes; it can even be brought up to the welding spot without losing the clamp. This is

allows for safer delivery.

In the Z direction, the LD panel can also be raised to compensate for cross wire diameters if the diameter of the cross wires should change. A compensation in the Z-direction can also be achieved in detail from a number of other factors,

the variability of the machine and the quality of the

The longitudinal wire guide 4 can push further longitudinal wires 6 along the front side of the family of longitudinal rods in the X-direction for the purpose of welding without overlap. Finally, guide units can also hold the lattice structure of cross-wire magnets
